No. 14/350,687, filed Apr. 9, 2014, which is the U.S. National Stage of PCT/US12/59680, filed Oct. 11, 2012, which claims the benefit of priority of U.S. Provisional Application No. 61/547,667, filed Oct. 14, 2011. The entirety of the foregoing is expressly incorporated herein by reference.

BACKGROUND

This patent is directed to an injector and a method of assembling the injector, and, in particular, to a prefilled injector and a method of assembling the prefilled injector.

Injectors are used to deliver medical fluids, such as liquid drugs, to a patient. In particular, the injector will provide the fluid to the patient through a needle, cannula or catheter that defines a flow path into the patient. Certain injectors have a reservoir that is assembled by the manufacturer already connected to the flow path. However, these reservoirs are typically provided empty by the manufacturer to the patient or healthcare provider (e.g., doctor, nurse, healthcare assistant, etc.), and then the reservoir is filled at the time of use. Alternatively, the injector may be used in combination with a reservoir that is provided to the patient or healthcare provider prefilled.

In either case, the injector must be prepared prior to use. For example, if the reservoir is provided empty, then the reservoir must be filled. To do this, a syringe is filled with the drug to be delivered, and then the drug is injected into the reservoir through an inlet port. Prior to the injection, the inlet port must be sterilized by swabbing the outer surface with an alcohol wipe, for example. Similarly, before the prefilled reservoir is connected to the flow path in the alternative injector, the mating connectors must be sterilized, by swabbing the surface with an alcohol wipe.

In either event, the use of the injector requires additional material and time.

As set forth in more detail below, the present disclosure sets forth an improved injector embodying advantageous alternatives to the conventional devices and methods discussed above.

DETAILED DESCRIPTION OF VARIOUS EMBODIMENTS

Although the following text sets forth a detailed description of different embodiments of the invention, it should be understood that the legal scope of the invention is defined by the words of the claims set forth at the end of this patent. It should also be understood that, unless a term is expressly defined in this patent using the sentence “As used herein, the term ‘______’ is hereby defined to mean . . . ” or a similar sentence, there is no intent to limit the meaning of that term, either expressly or by implication, beyond its plain or ordinary meaning, and such term should not be interpreted to be limited in scope based on any statement made in any section of this patent (other than the language of the claims). To the extent that any term recited in the claims at the end of this patent is referred to in this patent in a manner consistent with a single meaning, that is done for sake of clarity only so as to not confuse the reader, and it is not intended that such claim term be limited, by implication or otherwise, to that single meaning. Finally, unless a claim element is defined by reciting the word “means” and a function without the recital of any structure, it is not intended that the scope of any claim element be interpreted based on the application of 35 U.S.C. § 112, sixth paragraph.

The detailed description is to be construed as exemplary only and does not describe every possible embodiment of the invention because describing every possible embodiment would be impractical, if not impossible. Numerous alternative embodiments could be implemented, using either current technology or technology developed after the filing date of this patent, which would still fall within the scope of the claims defining the invention. Along these lines then, several embodiments according to the present disclosure are illustrated in FIGS. 1-3 and 5-15.

In general terms, an injector according to the present disclosure includes a container, a fluid delivery system and an actuator. While reference is made to an injector, which in some instances may refer to a delivery device that ensures that a set volume of drug product is delivered, it will be understood that this disclosure also encompasses infusion devices, which in some instances may refer to a delivery device that ensures that a particular rate of delivery is achieved. It should also be understood that the terms injector and infuser may be used interchangeably when referring to embodiments in the specification.

As illustrated in FIGS. 1-3 and 5-11, the container may include a wall with an interior surface and a seal assembly with an interior surface, the interior surfaces of the wall and the seal assembly defining a closed sterile reservoir filled with a drug product. Moreover, the fluid delivery system illustrated in these embodiments may include a clean, unsheathed, rigid container needle having a point disposed only partially through the seal assembly in a storage state, and disposed through the interior surface of the seal assembly into the sterile reservoir in a delivery state. The injector may also include an actuator that is adapted to move the container needle from the storage state to the delivery state, which may involve movement of the needle relative to the container or of the container relative to the needle, as is discussed in greater detail below.

As is illustrated in FIGS. 1, 3, and 4-6, the seal assembly may be a flexible unitary wall having an interior surface that defines the interior surface of the seal assembly, and the point of the container needle may be disposed partially into the unitary wall. Alternatively, as illustrated in FIGS. 7-11, the seal assembly may include a flexible wall with an interior surface that defines the interior surface of the seal assembly, and a clean barrier disposed exterior of the flexible wall to define an enclosed clean space between the flexible wall and the clean barrier. According to such embodiments, the point of the container needle is disposed through the clean barrier into the clean space in the storage state.

Still further alternatives will be discussed in the context of each of the embodiments illustrated herein.

Referring then to FIG. 1, an injector 100 is illustrated therein. The injector 100 includes a container 102, a fluid delivery system 104, and an actuator 106.

The container 102 (which also may be referred to as a cartridge herein) includes a wall 110 with an interior surface 112 and an exterior surface 114. While a unitary (i.e., one-piece) wall 110 has been illustrated in FIG. 1 that defines both the interior and exterior surfaces 112, 114, it will be understood that according to other embodiments the wall 110 may include a plurality of layers with different layers defining the interior and exterior surfaces 112, 114.

According to certain embodiments of the present disclosure, the wall 110 is rigid. According to other embodiments, the wall 110 may be flexible, whether according to the nature of the material that defines the wall or according to the nature of the structure of wall (e.g., a bellows construction). The wall 110 may be made of glass, metal, or polymer, for example. In particular, polymer versions may be made of polycarbonate, polypropylene, polyethylene (such as high density polyethylene), polytetrafluoroethylene, cyclic olefin polymer, cyclic olefin copolymer, Crystal Zenith olefinic polymer (available from Daikyo Seiko, Ltd., Japan), nylon, or engineering resins, for example. As to flexible versions of the wall 110, butyl rubber, silicon-based rubber, latex-based rubber, coated rubber, as well as multi-layer polymer films, such as may include polyethylene (such as low density polyethylene) and polypropylene, may be used.

The wall 110 may have a generally cylindrical shape, which a shoulder 120 separating a first cylindrical section 122 having a first cross-sectional diameter from a second cylindrical section 124 having a second cross-sectional diameter, the first cross-sectional diameter being smaller than the second cross-sectional diameter. The wall 110 may also define two opposed, open ends 126, 128. The wall 110, or more particularly the interior surface 112 of the wall 110, may also define a bore 130.

The container 102 may include a flexible unitary wall 140 (which may also be referred to as a seal or septum) having an interior surface 142 and an exterior surface 144. The wall 140 may be disposed in the first open end 126 defined by the wall 110 and fixedly attached to the wall 110 of the container 102 such that there is limited relative movement between the wall 140 and the wall 110, for example at the points of attachment of the wall 140 to the wall 110 across the open end or opening 126. Moreover, the interior surfaces 112, 142 of the wall 110 and the flexible wall 140 may define, at least in part, a closed sterile reservoir 150 that is filled with a drug product 160, described in greater detail below. The wall 140 may be made of bromobutyl, chlorobutyl, or chlorobromobutyl rubber, fluoropolymer rubber, natural rubber, silicon-based rubber, silicon, or santoprene, for example.

The container 102 may also include a stopper or piston 170 with interior and exterior surfaces 172, 174. The piston 170 may be received within the end 128 defined by the wall 110, and may be moveable along the bore 130 between the ends 126, 128 of the container 102. According to such an embodiment, the reservoir 150 within which the drug product 160 is disposed may be defined by the interior surfaces 112, 142, 172 of the walls 110, 140 and piston 170.

The container 102 may be used in conjunction with the fluid delivery system 104, the relevant portions of which are illustrated in FIG. 1. In particular, the fluid delivery system 104 may include a clean, unsheathed, rigid container needle 180 having a point 182. As illustrated, the point 182 is disposed only partially into the flexible wall 140 in a storage state. The penetration of the point 182 of the needle 180 into the wall 140 may be controlled through a number of methods and/or mechanisms. For example, FIG. 2 illustrates a jig that may be used in combination with the container 102 to control the depth to which the point 182 penetrates the wall 140.

The fluid delivery system 104 may also include an injection needle 190 with a point 192. The point 192 of the injection needle 190 may be covered with a needle shield 194 to prevent contact with and contamination of the point 192. The container needle 180 and the injection needle 190 may be connected by a cannula or tube 200, which may be a flexible cannula according to certain embodiments of the present disclosure. The needle 190, like the needle 180, may be made of stainless steel, for example.

Fluid delivery system 104 may be used in conjunction with the actuator 106, mentioned previously and illustrated schematically in FIG. 1. The actuator 106 may be adapted to move the container needle 180 between the storage state illustrated in FIG. 1 and a delivery state illustrated in FIG. 3. In the delivery state, the container needle 180 is disposed through the interior surface 142 of the flexible wall 140 into the sterile reservoir 150.

The movement of the needle 180 between the states may occur in a variety of fashions. For example, the needle 180 may be held fixed relative to the housing of the injector 100, and the container 102 may move relative to the needle 180 and the housing. Alternatively, the container 102 may be held fixed relative to the housing, and the needle 180 may be moved relative to the container 102 and the housing. It may also be possible for both container 102 and needle 180 to move relative to the housing of the injector 100. It will be understood that all of these actions may be embraced within the statement that the actuator 106 is adapted to move the container needle 180 between the storage and delivery states.

The actuator 106 may be mechanical, electro-mechanical, or electrical. For example, the actuator 106 may include a solenoid, motor-driven lever, motor with associated gearing, etc. It may even be possible to provide a tab or button attached to the container 102 or the needle 180 to permit the user to achieve the relative motion between the container 102 and the needle 180 manually. In fact, the container 102 may be received within a tab or button that is depressed into the housing when the injector 100 is activated to move the container 102 relative to the (fixed) needle 180.

The actuator 106 may move the container needle 180 between storage and delivery states by moving the needle 180 from the storage state to the delivery state, or by moving the needle 180 from the delivery state to the storage state. In fact, the actuator may move the container needle 180 between the storage and delivery states repeatedly (i.e., multiple times or repetitions). Furthermore, the actuator 106 may move the container needle 180 immediately upon receipt of an input or signal (e.g., as generated through the depression or manipulation of a button, switch or other input device, which may be mechanical, electro-mechanical or electrical in nature, coupled to the actuator 106), or may delay movement of the container needle 180 between storage and delivery states some period of time after an input is received. According to a particular embodiment, the actuator 106 may delay movement of the needle 180 from the storage state to the delivery state until after such a time delay.

As mentioned previously, the reservoir 150 is described as sterile, while the container needle 180 is described as clean. These terms describe the condition of the reservoir 150 or the needle 180 as a consequence of their assembly under conditions that will ensure a specified level of freedom from contamination, wherein a sterile object or device is understood to have a relatively higher level of freedom from contamination than a clean object or device. By way of non-limiting example, the concepts of sterility and cleanliness may be discussed with reference to the schematic of FIG. 4, which discussion will be recognized applies not only to the embodiment illustrated in FIGS. 1 and 3, but all of the embodiments described herein.

FIG. 4 illustrates a manufacturing facility 250, and may be used to discuss a manufacturing process that is conducted within the facility 250. It will be noted that the facility 250 is divided into a plurality of spaces 252, 254, 256, 258, 260, 262, 264, 266, 268, which divisions may be maintained through the use of permanent or semi-permanent walls or other barriers. As will be understood, certain spaces or regions may be divided without barriers or walls, but may simply be separated on an organizational level instead. Additionally, it will be recognized that a greater or lesser number of spaces or an alternative arrangement of the spaces may be used, such differing numbers or arrangements of spaces being readily determinable by one of ordinary skill in the art.

The components of the container 102 (walls 110, 140, and stopper/piston 170) would enter the facility 250 through space 252, wherein the components are sterilized using e-beam technology, for example. Alternatively, the container components may be sterilized through other currently-known (e.g., treatment with chlorine dioxide or vapor phase hydrogen peroxide) or later-developed sterilization procedures as the components enter the facility 250 at entry points 252, 264, 266. The container 102 would then pass into space 254 for filing with the drug product. The space 254 may be operated as an aseptic Class 100 clean room. A Class 100 clean room is one in which the number of particles of size 0.5 μm or larger permitted per cubic foot of air is less than 100. Once the fill has been performed and the stopper 170 has been disposed in the end 128 of the container 102, the container 102 and drug product 160 is moved through transfer space 256 (also operated as a Class 100 clean room, wherein certain embodiments are also aseptic) before being received within storage space 258.

The containers 102 move from the storage space 258 into inspection area 260 (aseptic in certain embodiments), wherein the containers 102 are inspected prior to assembly with the fluid delivery system 104, actuator 106 and other elements of the injector 100. Because the drug product 160 is contained within the sealed container 102 at this point, the inspection area may be operated as a Class 10,000 clean room. Once inspected, the prefilled, sterile container 102 may be passed from inspection space 260 to assembly space 262.

Similar to the inspection space 260, the assembly space 262 may be operated as an aseptic Class 10,000 clean room. Materials being passed into the clean room from spaces 264, 266 may be in a sterile condition, or may be sterilized using e-beam technology, for example. Within the assembly space 262, the fluid delivery system 104 is connected to the container 102 once the surface 144 of the wall/septum 140 has been sterilized by swabbing the surface 144 with an alcohol wipe, for example. Because of the lower level of cleanliness, the fluid delivery system 104 may be referred to as clean, but not necessarily as sterile. However, because the container needle 180 does not penetrate through the wall 140, the reservoir 150 and the drug product 160 remains sterile (i.e., at the higher level of cleanliness). The remainder of the injector 100 may also be assembled in this space 262 prior to the injector 100 passing into the packaging space 268, with certain aspects of the injector (e.g., the actuator 106) potentially being assembled with the container 102 or the fluid delivery system 104 prior to the assembly of the container 102 and the fluid delivery system 104.

It will be recognized that the embodiment of the injector 100 illustrated in FIGS. 1 and 3 is simply an exemplary embodiment according to the present disclosure. To this end, FIGS. 5 and 6 illustrate variants of the injector illustrated in FIGS. 1 and 3.

According to the embodiment of FIG. 5, the injector 300 includes a container 302, a fluid delivery device 304 and an actuator 306. Similar to the embodiment of FIGS. 1 and 3, the container 302 includes a wall 310 with interior and exterior surfaces 312, 314. Moreover, the wall 310 may have two opposed ends 320, 322 with the interior surface 312 of the wall 310 defining a bore 324 between the opposing ends 320, 322.

However, unlike the container 102, the container 302 has a fixed plug 326 that closes the end 320. In addition, while the container 302 has a flexible unitary wall 330 with interior and exterior surfaces 332, 334, the wall 330 is disposed within the end 322 of the container 302, and thus performs the role of the stopper/piston 170 in the container 102. Consequently, the wall 330 is moveable along the bore 324 between the opposing ends 320, 322. Moreover the interior surfaces 312, 332 of the walls 310, 330 define a sterile reservoir 340 in which a drug product 350 is disposed.

According to this embodiment, the fluid delivery device 304 may include a clean, unsheathed, rigid container needle 360 having a point 362. The point 362 of the needle 360, like the point 182 of the needle 180, is disposed only partially into the flexible wall 330 in a storage state, with the actuator 306 causing the point 362 to move between the storage state and a delivery state wherein the point 362 is disposed through the interior surface 332 of the flexible wall 330 into the sterile reservoir 340. The container needle 360 may be in fluid communication with a injection needle 370 having a point 372 covered with a shield 374 through a cannula 380 received within a piston rod 382, for example, which rod 382 may be used to move the stopper/piston 330 between the ends 320, 322 of the container 302.

FIG. 6 shows a closely related variant to that illustrated in FIG. 5. According to the variant illustrated in FIG. 6, a container has a wall 390 with interior and exterior surfaces 392, 394. However, unlike the containers discussed previously, the wall 390 defines a closed end 396 and an open end 398. The container also includes a flexible wall 400, like the wall 330 of the embodiment of FIG. 5, which wall 400 is moveable within the container between the open end 398 and the closed end 396. According to this embodiment, a separate structure is not required to close off one of the ends 396, 398 because the wall 390 already defines the closed end 396 itself. For that matter, the closed end 396 may be resized so that it is radially larger than illustrated in FIG. 6.

Having thus discussed a plurality of embodiments wherein a seal assembly includes only a flexible unitary wall, a further plurality of embodiments will be discussed with reference to FIGS. 7-11 wherein the seal assembly includes a plurality of walls and/or seals. This structure may also be referred to as a compartmentalized seal (or septum with reference to FIG. 7, or stopper with reference to FIGS. 8-11).

Referring first to FIG. 7, an injector 450 includes a container 452, a fluid delivery system 454, and an actuator 456.

The container 452 includes a wall 460 with an interior surface 462 and an exterior surface 464. Like the container of FIGS. 1 and 2, the wall 460 may have a generally cylindrical shape, with a shoulder 470 separating a first cylindrical section 472 having a first cross-sectional diameter from a second cylindrical section 474 having a second cross-sectional diameter, the first cross-sectional diameter being smaller than the second cross-sectional diameter. The wall 460 may also define two opposed, open ends 476, 478. The wall 460, or more particularly the interior surface 462 of the wall 460, may also define a bore 480.

Unlike the container 102 of FIGS. 1 and 3, the container 452 of FIG. 7 has a seal assembly that includes more than a single, unitary wall. The seal assembly of the container 452 includes a flexible wall 490 and a clean barrier 492. The flexible wall 490 has an interior surface 494 and an exterior surface 496, while the clean barrier 492 has an interior surface 498 and an exterior surface 500. The interior surfaces 462, 494 of the wall 460 and the flexible wall 490 defining a closed sterile reservoir 510 filled with a drug product 520. On the other hand, the clean barrier 492 is disposed exterior of the flexible wall 490 to define an enclosed clean space 530 between the flexible wall 490 and the clean barrier 492. The clean space 530 may be defined by the interior surface 462 of the wall 460, the exterior surface 496 of the flexible wall 490, and the interior surface 498 of the clean barrier 492.

As illustrates, the container 452 may also include a stopper or piston 540 with interior and exterior surfaces 542, 544. The piston 540 may be received within the end 478 defined by the wall 460, and may be moveable along the bore 480 between the ends 476, 478 of the container 452. According to such an embodiment, the reservoir 510 within which the drug product 520 is disposed may be defined by the interior surfaces 462, 494, 542 of the walls 460, 490 and piston 540.

The embodiment of FIG. 7 also includes the fluid delivery system 454 comprising a clean, unsheathed, rigid container needle 550 having a point 552 disposed through the clean barrier 492 into the clean space 530 in a storage state, and disposed through the interior surface 494 of the flexible wall 490 into the sterile reservoir 510 in a delivery state. In this sense, the container needle 550 only partially penetrates the seal assembly. The fluid delivery system 454 may also include an injection needle 560 with a point 562 covered at least initially with a needle shield 564 to prevent contact with and contamination of the point 562. The container needle 550 and the injection needle 560 may be connected by a cannula or tube 570, which may be a flexible cannula according to certain embodiments of the present disclosure.

As was the case with the embodiment of FIGS. 1 and 3, the present disclosure includes a number of variants for the embodiment illustrated in FIG. 7, which variants are illustrated in FIGS. 8-11.

The embodiment of FIG. 8 is similar to the embodiment of FIG. 7 in the way that the embodiment of FIG. 5 was similar to that of FIGS. 1 and 3. In particular, the seal assembly of an injector 600 according to the embodiment of FIG. 8 is disposed in a container 602 in place of the stopper/piston 540 illustrated relative to the container 452. That is, the container 602 includes a wall 604 that defines a bore 606, and a flexible wall 608 and a clean barrier 610 each define a stopper that is moveable along the bore 606. While the wall 604 of the container 602 does not define opposing open and closed ends in the embodiment illustrated, such an alternative is possible according to the present disclosure similar to FIG. 6.

FIGS. 9-11 illustrate variants to the embodiment illustrated in FIG. 8, which variants include additional features to permit the space or region between the flexible wall and the clean barrier to be evacuated or exhausted. These additional features may be referred to as vents, valves or bypasses, but all of these structures permit gases to escape from the space or region between the flexible wall and the clean barrier when an actuator moves the associated container needle from a storage state to a delivery state. This is not to suggest that the inner wall and exterior barrier cannot remain separated, for example through the use of a spacer or spacers, according to other embodiments of the present disclosure. However, the alternatives of FIGS. 9-11 illustrate options for evacuating the clean space as to those embodiments where the inner wall and exterior barrier come together.

A container 650 is illustrated in FIG. 9 including a wall 652 and a seal assembly, the assembly including a flexible wall 654 and a clean barrier 656. The flexible wall 654 has an interior surface 658 and an exterior surface 660, while the clean barrier 654 has an interior surface 662 and an exterior surface 664. An interior surface 668 of the wall 652 and the interior surface 658 of the flexible wall 654 defining a closed sterile reservoir 670 filled with a drug product 680. On the other hand, the clean barrier 656 is disposed exterior of the flexible wall 654 to define an enclosed clean space 690 between the flexible wall 654 and the clean barrier 656. The clean space 690 may be defined by the interior surface 668 of the wall 652, the exterior surface 660 of the flexible wall 652, and the interior surface 662 of the clean barrier 656.

As is also illustrated in FIG. 10, a fluid delivery system 700 including a container needle 702 is used in conjunction with the seal assembly. The container needle 702 is illustrated in the storage state, wherein the container needle 702 is disposed through the clean barrier 656 so that a point 704 of the needle 702 is disposed in the clean space 690. The point 704 will penetrate the flexible wall 654 and depend into the reservoir 670 in a delivery state, not shown. It will be recognized that the needle 702 is not drawn to scale particularly as to its length, as is true of other embodiments illustrated here.

In contrast with the previously discussed embodiments, the container 650 illustrated in FIG. 9 includes at least one vent 710. The vents 710 are in fluid communication with the clean space 690 between the clean barrier 656 and the flexible wall 654. The vents 710 are selectively actuated to permit gas trapped between the clean barrier 656 and the flexible wall 654 to escape through the vents 710 when the seal assembly is moved between the illustrated storage state and the delivery state, wherein the clean barrier 656 is advanced in the direction of the flexible wall 654 to permit the point 704 of the container needle 702 to penetrate through the wall 654. However, the vents 710 may be in a sealed condition relative to the environment until actuated, for example, by a change in the pressure within the clean space 690.

As illustrated, the vents 710 are disposed within the clean barrier 656, and extend between the interior surface 662 and the exterior surface 664 of the barrier 656. A flap 712 covers the end of the vent 710 proximate to the exterior surface 664, and thereby seals the end of the vent 710 until the vent is actuated, preserving the cleanliness of the space 690 between the clean barrier 656 and the flexible wall 654. Alternatively, the vents 710 may be arranged, for example, in the wall 652 of the container 650.

FIGS. 10 and 11 illustrate a further variant on the system of FIG. 8, wherein a container 720 includes a wall 722 and a seal assembly, the assembly including a flexible wall 724 and a clean barrier 726. The flexible wall 724 has an interior surface 728 and an exterior surface 730, while the clean barrier 726 has an interior surface 732 and an exterior surface 734. An interior surface 738 of the wall 722 and the interior surface 728 of the flexible wall 724 define a closed sterile reservoir 740 filled with a drug product 750. On the other hand, the clean barrier 726 is disposed exterior of the flexible wall 724 to define an enclosed clean space 760 between the flexible wall 724 and the clean barrier 726. The clean space 760 may be defined by the interior surface 738 of the wall 722, the exterior surface 730 of the flexible wall 722, and the interior surface 732 of the clean barrier 726.

As is also illustrated in FIG. 10, a fluid delivery system 770 including a container needle 772 is used in conjunction with the seal assembly. The container needle 772 is illustrated in the storage state, wherein the container needle 772 is disposed through the clean barrier 726 so that a point 774 of the needle 772 is disposed in the clean space 760. The point 774 will penetrate the flexible wall 724 and depend into the reservoir 740 in a delivery state, not shown.

In contrast with the previously discussed embodiments, the container 720 illustrated in FIG. 10 includes at least one bypass or vent 780. The bypasses 780 are in fluid communication with the reservoir 740. The bypasses 780 are selectively actuated to permit gas trapped between the clean barrier 726 and the flexible wall 724 to escape through the bypasses 780 into the reservoir 740 when the seal assembly is moved between the illustrated storage state and the delivery state, wherein the clean barrier 726 is advanced in the direction of the flexible wall 724 to permit the point 774 of the container needle 772 to penetrate through the wall 724.

However, the bypasses 780 are not in fluid communication with the clean space 760 until the flexible wall 724 has moved from the storage state illustrated in FIG. 10 to an intermediate state illustrated in FIG. 11. As illustrated in FIGS. 10 and 11, the bypasses 780 may be defined in the interior surface 738 of the wall 722, and as illustrated may take the form of a groove 782 formed in the wall 722. The groove 782 may have a distal end 784 and a proximal end 786. As will be recognized, until the exterior surface 730 of the flexible wall 724 moves past the distal end 784 of the grooves 782, the reservoir 740 is in a sealed condition relative to the clean space 760. However, once the exterior surface 730 of the flexible wall 724 moves past distal end 784 of the grooves 782, the gases trapped between the clean barrier 726 and the flexible wall 724 may exhaust into the reservoir 740. This may facilitate the movement of the barrier 726 and needle 770 toward the flexible wall 724.

While all of the forgoing embodiments have focused to one degree or another on a fluid delivery system partially disposed through a seal assembly, there are other alternatives where the container needle is not disposed through the seal assembly, or where the container needle is disposed fully through the seal assembly. Three such alternatives are illustrated in FIGS. 12-14.

FIG. 12 illustrates an injector 800 with a container 802, a fluid delivery system 804 and an actuator 806. Similar to the embodiments illustrated above, the actuator 806 would cause the fluid delivery system 804 to be disposed through a seal assembly associated with the container 802 in a delivery state, and thereby be in fluid communication with the interior of the container 802. However, as mentioned above, in the storage state illustrated in FIG. 12, the fluid delivery system is not even partially disposed through the seal assembly.

To this end, the container 802 includes at least a flexible wall 810, which may be in the form of a septum or a stopper according to the present disclosure. The flexible wall 810 has an interior surface 812 and an exterior surface 814. Additionally, the fluid delivery system 804 includes a container needle 816, an injection needle 818, and a flexible conduit 820 connecting the container needle 816 and the injection needle 818. Both the container needle 816 and the injection needle 818 are received within a cover 822, 824 that preserves the cleanliness of the needle 816, 818. The cover 822 may be referred to as a cap, while the cover 824 may be referred to as a shield. Also included is an alcohol wipe 826 disposed between the flexible wall 810 and the cover 822, which wipe 826 may be kept in an air-tight condition to maintain alcohol saturation.

According to the present disclosure, prior to initiating action of the actuator 806, the wipe 826 is drawn out from between the flexible wall 810 and the cover 822. For example, an end of the wipe 826 may be disposed outside housing of the injector 800 to permit the end to be grasped and the wipe 826 pulled out from the injector 800. Alternatively, the end of the wipe 826 may be attached to another aspect of the injector 800, such as a liner that covers an adhesive surface of the injector 800 that will be attached to the patient, such that when the liner is removed to expose the adhesive surface, the wipe 826 is pulled out from the injector 800 as well. The removal of the wipe sterilizes surface 814 of the wall 810 and opposing surface 828 of the cap 822. The actuator 806 then moves the container needle 816 through the cap 822 and the flexible wall 810.

FIGS. 13 and 14, on the other hand, illustrated embodiments wherein the container needle is disposed through the flexible wall (defining the stopper or septum) and a valve is used to seal the reservoir off from the injection needle. The valve may also be used to control the flow of drug product from the reservoir in the container. In this fashion, the valve may be used to meter an amount of drug product from the reservoir, or to delay the flow of the drug product until a time delay has elapsed relative to receipt of an input from an input device (e.g., button or switch), for example.

As such, FIG. 13 illustrates an injector 850 with a container 852, a fluid delivery system 854 and an actuator 856. The container 852 includes at least a flexible wall 860, which may be in the form of a septum according to the illustrated embodiment. The flexible wall 860 has an interior surface 862 and an exterior surface 864. Additionally, the fluid delivery system 854 includes a container needle 866, an injection needle 868, and a flexible cannula or tubing 870 connecting the container needle 866 and the injection needle 868. The injection needle 868 may be received within a cover 872 that preserves the cleanliness of the needle 868.

On the other hand, the container needle 866 (and in particular a point 874 of the container needle 866) is disposed through the flexible wall 860 through the interior surface 862. The needle 866 is thus in fluid communication with a sterile reservoir 880 and a drug product 890 disposed within the reservoir 880. Fluid communication between the container needle 866 and the injection needle 868 is interrupted by a valve 900 disposed in or along the flexible tubing 870, which valve 900 may define a boundary between the sterile portion of the injector 850 and the clean portion of the injector 850. Thus, unlike the other embodiments discussed above relative to FIGS. 1-12, the actuator 856 of the injector 850 is not used to move the container needle 866 relative to the flexible wall 860, but instead to manipulate the valve between a closed state wherein fluid communication is interrupted between the needles 866, 868 and an open state wherein the container needle 866 is in fluid communication with the injection needle 868.

It will be recognized that the valve 900 may take a variety of shapes and forms, two of which are illustrated in FIGS. 13 and 14. In particular, FIG. 13 illustrates an embodiment of the injector 850 wherein a rotatable valve 900 is disposed in the flexible tubing 870, or has an internal valve member that is in fluid communication with the fluid flow path defined between the container needle 866 and the injection needle 868. FIG. 14, by contrast, illustrates and embodiment of the injector wherein a pinch valve 902 is disposed along the flexible tubing 870, and thus cooperates with an exterior surface of the tubing 870 to interrupt the fluid communication between the container needle 866 and the injection needle 868.

Embodiments such as are illustrated in FIGS. 13 and 14 would also work well with a container that has a permanently attached needle, such that the container is in the form of a syringe, for example.

It will be further understood that the embodiments illustrated in FIGS. 13 and 14 may be further modified to incorporate a seal assembly including a plurality of walls and/or seals, such as is illustrated in FIG. 7, for example. FIG. 15 illustrates such an embodiment.

In particular, FIG. 15 illustrates an injector 920 with a container 922, a fluid delivery system 924, an actuator 926, and a seal assembly 928. The fluid delivery system 924 may include a container needle 930, an injection needle 932, and a flexible cannula or tubing 934 connecting the container needle 930 and the injection needle 932. The injection needle 932 may be received within a cover 936 that preserves the cleanliness of the needle 932. The needle 932 may also be in selective fluid communication with a sterile reservoir 940 and a drug product 942 disposed within the reservoir 940 via a valve 944 disposed in or along the flexible tubing 934. In this regard, the injector 920 is similar to those illustrated in FIGS. 13 and 14.

However, the seal assembly 928 of the injector 920 also has a flexible wall 950 and a clean barrier 952. The flexible wall 950 and the clean barrier 952 each have interior and exterior surfaces, with the interior surface of the flexible wall 950 defining, in part, the closed sterile reservoir 940. On the other hand, the clean barrier 952 is disposed exterior of the flexible wall 950 to define an enclosed clean space 954 between the flexible wall 950 and the clean barrier 952 in which a point 956 of the container needle 930 may be disposed.

In this regard, the embodiment of FIG. 15 has two potential barriers: one in the form of the valve 944 and a second in the form of the placement of the point 956 within the clean space 954. In fact, the valve 944 may be controlled to provide a delay in the injection of the drug product 942 after the container needle 930 has been caused to penetrate trough the flexible wall 950 into the reservoir 940.

As will be recognized, the devices according to the present disclosure may have one or more advantages relative to conventional technology, any one or more of which may be present in a particular embodiment in accordance with the features of the present disclosure included in that embodiment. As one example, these embodiments maintain the sterility of the drug product until the time of use. As another example, the potential for mixing of the drug product is limited or eliminated prior to the time of use. As a still further example, unintended delivery of the drug product is limited or prevented prior to the time of use.

For illustrative purposes only, FIG. 16 provides a further method 1000 for assembling delivery devices according to any of the embodiments disclosed above. The method 1000 follows the general processing flow outlined above relative to FIG. 4. However, rather than referring to the cleanroom classifications according to U.S. Federal Standard 209E, reference is made to cleanroom classifications according to the GMP EU standard. Moreover, the method 1000 provides additional optional paths (represented as a left or right branch) that may be followed in the assembly of the delivery device. Consequently, the method 1000 of FIG. 16 may be viewed as supplementary to the discussion above relative to FIG. 4.

The method 1000 for assembling delivery devices begins at block 1002. The containers used in the device are initially stored in sealed tubs. As mentioned above, these containers may be or may have been sterilized at some point. At block 1002, the tubs are debagged, for example using an automated debagger in a Grade C cleanroom. At block 1004, the Tyvek seal is peeled off (e.g., by a robot) and removed, for example, in a space operated as a Grade A cleanroom, perhaps within an isolator in a space otherwise operated a Grade C cleanroom.

The containers are filled and stoppers are attached, and then the containers are re-nested in open tubs, at block 1006, in a space operated as a Grade A cleanroom, perhaps within an isolator in a space otherwise operated a Grade C cleanroom. From this point, two different alternative paths, or branches, are possible.

The filled containers may be left in the open tubs at block 1008. The tubs may be conveyed and carted to a storage space (e.g., cold room) at block 1010.

If the route of block 1008, 1010 is followed, then the method 1000 may continue with the tubs being transferred for processing to an inspection room at block 1012. The filled containers are then denested from the open tubs at block 1014, and supplied to an automated inspection machine at block 1016. Automated inspection of the filled containers occurs at block 1016, followed by optional, additional semi-automated or manual inspection at block 1018.

Alternatively, the tubs may be resealed, rebagged, and labeled, at block 1020. For example, the tubs may be resealed with Tyvek (e.g., using a Bausch+Strobel tub sealer), rebagged, and then labeled in a Grade C cleanroom at block 1020. The tubs may then be stored, or even shipped, if necessary, at blocks 1022, 1024.

Once storage or transport is completed, the tubs are debagged, for example using an automated debagger at block 1026. At block 1028, the Tyvek seal is peeled off and removed. The filled containers may then be denested for inspection, at block 1030. The actions at blocks 1026, 1028, 1030 are performed in a Grade C cleanroom. An automated inspection may then be carried out using a visual inspection machine designed for operation in a Grade C cleanroom at block 1032.

Following either procedure, the filled, inspected containers may then be transferred to rondo trays at block 1034.

According to a first procedure, the rondo trays may be sent directly to storage at block 1036. If the route of block 1036 is followed, then the rondo trays are transferred for processing to the device assembly room at block 1038. The containers are denested at block 1040, and assembled with the other elements of the delivery device at block 1042 to define an assembled delivery device (e.g., an injector or an infuser).

Alternatively, the containers may be moved into tubs, which are sealed, bagged, and labeled, at block 1044. For example, the tubs may be resealed with Tyvek, bagged, and then labeled in a Grade C cleanroom. The tubs may then be stored, or even shipped for further processing, if necessary, at blocks 1046, 1048. Once storage or transport completed, the tubs are debagged, for example using an automated debagger at block 1050. At block 1052, the Tyvek seal is peeled off and removed, and the containers are denested. The filled containers may then be assembled with the other elements of the delivery device at block 1054. The actions at blocks 1050, 1052, 1054 may all occur in a Grade C cleanroom.

In either event, the assembled devices are packaged at block 1056, and the packaged, assembled devices are stored at block 1058. Finally, the packaged, assembled devices are transported to the distributor, and/or for other distribution actions at block 1060.

Other advantages not specifically listed herein may also be recognized as well. Moreover, still other variants and alternatives are possible.

As an example, while the operation of the actuator has been described in regard to the foregoing embodiments as moving, for example, the container needle from a storage state to a delivery state, it will be understood that the actuator may also move the container needle from the delivery state to the storage state. For example, if a dose of drug product is to be delivered that is less than the volume of the reservoir (such as may be the case wherein the injector is designed to be programmed to deliver an adjustable dose according to the needs of the patient (e.g., pediatric vs. adult patient)), then the actuator may move the container needle from the storage state to the delivery state prior to delivery of the dose, and from the delivery state to the storage state after delivery of the dose. The movement from the delivery state to the storage state will in effect reseal the container and close the fluid path to the patient. This sequence of movement between the storage state and the delivery state may be repeated. As noted above, maintaining a closed fluid path until delivery is initiated is advantageous in that the opportunity for unintended delivery of the drug product to the patient and/or mixing of the drug product with the patient's bodily fluids is reduced.

The injectors according to the present disclosure may be used with a variety of drug products, including colony stimulating factors, such as granulocyte colony-stimulating factor (G-CSF), may be administered to increase the number of immune cells (e.g., white blood cells) found in bone marrow or peripheral blood. Such G-CSF agents include, but are not limited to, Neupogen® (filgrastim) and Neulasta® (pegfilgrastim).

In other embodiments, the injector may be used with various other products including, for example, an erythropoiesis stimulating agent (ESA), which may be in a liquid or a lyophilized form. An ESA is any molecule that stimulates erythropoiesis, such as Epogen® (epoetin alfa), Aranesp® (darbepoetin alfa), Dynepo® (epoetin delta), Mircera® (methyoxy polyethylene glycol-epoetin beta), Hematide®, MRK-2578, INS-22, Retacrit® (epoetin zeta), Neorecormon® (epoetin beta), Silapo® (epoetin zeta), Binocrit® (epoetin alfa), epoetin alfa Hexal, Abseamed® (epoetin alfa), Ratioepo® (epoetin theta), Eporatio® (epoetin theta), Biopoin® (epoetin theta), epoetin alfa, epoetin beta, epoetin zeta, epoetin theta, and epoetin delta, as well as the molecules or variants or analogs thereof as disclosed in the following patents or patent applications: U.S. Pat. Nos. 4,703,008; 5,441,868; 5,547,933; 5,618,698; 5,621,080; 5,756,349; 5,767,078; 5,773,569; 5,955,422; 5,986,047; 6,583,272; 7,084,245; and 7,271,689; and PCT Publ. Nos.

An ESA can be an erythropoiesis stimulating protein. As used herein, “erythropoiesis stimulating protein” means any protein that directly or indirectly causes activation of the erythropoietin receptor, for example, by binding to and causing dimerization of the receptor. Erythropoiesis stimulating proteins include erythropoietin and variants, analogs, or derivatives thereof that bind to and activate erythropoietin receptor; antibodies that bind to erythropoietin receptor and activate the receptor; or peptides that bind to and activate erythropoietin receptor. Erythropoiesis stimulating proteins include, but are not limited to, epoetin alfa, epoetin beta, epoetin delta, epoetin omega, epoetin iota, epoetin zeta, and analogs thereof, pegylated erythropoietin, carbamylated erythropoietin, mimetic peptides (including EMP1/hematide), and mimetic antibodies. Exemplary erythropoiesis stimulating proteins include erythropoietin, darbepoetin, erythropoietin agonist variants, and peptides or antibodies that bind and activate erythropoietin receptor (and include compounds reported in U.S. Publ. Nos. 2003/0215444 and 2006/0040858) as well as erythropoietin molecules or variants or analogs thereof as disclosed in the following patents or patent applications: U.S. Pat.
